Process consultation as conceived and reformulated several times by Edgar Schein constitutes a seminal contribution to the process of organization development in general and to the definition of the helping role of the consultant in particular. Under the pressure of a pragmatic turn in organizational change work, the practice of process consultation was fading away during the eighties and nineties. In some particular training and organizational consulting contexts nevertheless, the foundational principles and practices of process consultation are experienced to be more relevant than ever before. A relational constructionist theoretical lens, an emphasis on joint consultant–client practices, and a proper contextual embedding constitute a relational practice perspective that embodies in a new form and language those foundational ideas.
